Why This Is the Best Potato Leek Soup Recipe

There are dozens of variations out there, from Julia Child’s potato leek soup to potato leek soup crock pot versions, but this one strikes the perfect balance between:

• Creamy but not heavy
• Flavorful but simple
• Easy enough for beginners
• Customizable (vegan, dairy-free, bacon-loaded, slow cooker friendly)

It’s the kind of soup that tastes like it simmered all day, even though it didn’t.

What Makes Leek and Potato Soup So Special?

Leeks are milder and slightly sweeter than onions, which gives this leek potato soup recipe its signature gentle flavor. When they cook down in butter, they become soft, silky, and aromatic, creating the perfect base for tender potatoes and savory broth.

Once blended, the texture becomes velvety smooth, like a cream of leek and potato soup you’d order at a cozy café.

What You’ll Need

Ingredients

• 3 tablespoons butter (or olive oil for dairy-free potato leek soup)
• 4 large leeks (white and light green parts only), chopped
• 3 cloves garlic, minced
• 2 pounds Yukon Gold potatoes, peeled and cubed
• 6–7 cups chicken or vegetable broth
• 2 bay leaves
• 2 sprigs fresh thyme
• 1 teaspoon salt
• ½ teaspoon black pepper
• ¾ to 1 cup heavy cream (optional but recommended)

Optional Garnishes:

• Crispy bacon (for potato bacon leek soup)
• Fresh chives
• Extra thyme
• Drizzle of olive oil

Step-by-Step Instructions

Clean the Leeks Properly (Important!)

Leeks hide dirt between their layers.

• Trim off the root ends and dark green tops.
• Slice lengthwise.
• Rinse thoroughly under cold running water, separating layers to remove grit.

This step makes all the difference in a clean, smooth soup.

Sauté the leeks

In a large Dutch oven or soup pot:

• Melt butter over medium heat.
• Add chopped leeks and garlic.
• Cook for 8–10 minutes until soft and fragrant (do not brown).

This builds the flavor foundation for your creamy potato leek soup recipe.

Add Potatoes & Broth

• Add potatoes, broth, bay leaves, thyme, salt, and pepper.
• Bring to a boil.
• Reduce the heat, cover, and simmer for 15–20 minutes until potatoes are fork-tender.

Blend Until Smooth

Remove bay leaves and thyme sprigs. Use:

• An immersion blender (easiest method), or
• A standard blender in batches (never fill more than halfway; vent lid slightly for safety).

Blend until completely smooth and creamy.

Add Cream & Adjust

Stir in heavy cream and simmer gently for 2–3 minutes. Taste and adjust seasoning.

If too thick → add more broth.
If too thin → simmer uncovered until thickened.
